In this work a novel ion imprinted polymer (IIP) based on N-(pyridin-2-ylmethyl)ethenamine (V-Pic) was coated on Fe3O4 nano-particles and characterized by thermal gravimetric and differential thermal analysis (TG/DTA), IR spectroscopy, Scanning electron microscopy (SEM) and also elemental analysis. The application of this novel magnetic sorbent was investigated in rapid extraction, preconcentra...

An ultrathin novel nanosensor (31.5 +/- 4.1 nm thick in the absence of analytes), employing a molecularly imprinted polymer as a recognition element for cholesterol and gold nanoparticle enhanced transmission surface plasmon resonance spectroscopy for detection, was constructed.

A facile, general, and highly efficient approach to obtain narrowly dispersed molecularly imprinted polymer microspheres with multiple stimuli-responsive template binding properties in aqueous media by successive RAFT polymerization is described.

Biodegradable polymer nanoparticles are promising carriers for targeted drug delivery in nanomedicine applications. Molecu- lar imprinting is a potential strategy to target polymer nanoparticles through binding of endogenous ligands that may promote recognition and active transport into specific cells and tissues. However, the lock-and-key mechanism of molecular imprinting requires relatively r...

The aim of this work was to investigate the possibility of employing semi-covalent molecularly imprinted polymers (MIPs) as a controlled release device for ibuprofen and naproxen in biological fluids, especially gastrointestinal ones, compared to non imprinted polymers (NIPs). The carboxyl groups of ibuprofen and naproxen were converted to vinyl ester group by reacting ibuprofen and vinyl aceta...

Here we introduce microelectrospotting as a new approach for preparation of protein-selective molecularly imprinted polymer microarrays on bare gold SPR imaging chips. During electrospotting both the gold chip and the spotting tip are electrically connected to a potentiostat as working and counter electrodes, respectively. The spotting pin encloses the monomer-template protein cocktail that upo...

The molecularly imprinted polymer (MIP) based on methacrylic acid functionalized β-cyclodextrin (MAA-β-CD) monomer was synthesized for the purpose of selective recognition of benzylparaben (BzP). The MAA-β-CD monomer was produced by bridging a methacrylic acid (MAA) and β-cyclodextrin (β-CD) using toluene-2,4-diisocyanate (TDI) by reacting the -OH group of MAA and one of the primary -OH groups ...

Optical trapping of particles has become a powerful non-mechanical and non-destructive technique for precise particle positioning. The manipulation of particles in the evanescent field of a channel waveguide potentially allows for sorting and trapping of several particles and cells simultaneously. This paper describes the studies carried out, both theoretically and experimentally, to optimise t...

Imprinted polymers are now being increasingly considered for active biomedical uses such as drug delivery. In this work, the use of molecularly imprinted polymers (MIPs) in designing new drug delivery devices was studied. Imprinted polymers were prepared from methacrylic acid (functional monomer), ethylene glycol dimethacrylate (cross-linker), and bromhexine (as a drug template) using bulk poly...
